QUESTION NO. 7

QUESTION: Councillor P. Holohan

To ask the Chief Executive how much monetary saving SDCC have saved on electricity since its switch to LED Streetlights?

REPLY:

There is no way to accurately calculate the monetary saving of installing LED Public Lighting on an ongoing basis as the savings will fluctuate in line with fluctuating energy tariffs.

We do know that LED lanterns use 50% of the energy compared to traditional SOX lanterns.

For the year 2024 we had 80% of our lanterns upgraded to LED and 20% were still traditional SOX lanterns. For that year, we spent approximately €1.8m on public lighting energy for our regional and local road network. If none of these lanterns were LED we would have spent an extra 65% (approx. €1.2m extra) on energy in 2024.
